To all whom it may concern:

Be it known that I, BnnNnARn BENEmcT, citizen of. the United States ofAmerica, residing at New York, in the county of New York and State ofNew York, have invented certain, new and useful Improvements inCircuit-Closers, of which the following is a specification.

The present invention pertains to electric flash light lamps, andparticularly to circuit closers or switches whereby the lamp may belighted o'rextinguished.

The hitherto used structures have been found objectionable because theswitch after a short time of use, becomes ineffective, as the parts wearoff very quickly. p

The object of my invention is to provide a switch that will be moredurable and simpler in construction. I

With this object in view, my invention consists in the construction,combination and arrangement of parts as hereinafter described and setforth in the claims.

To make my invention clear, I shall refer to 'the accompanying drawing,in which similar reference characters denote corresponding parts and inwhich Fi re 1 is a front elevation of my new switc as applied to thecasing, which is shown broken away at its ends; Fig. 2 is a longitudinalsection of the complete lamp taken on line 22 of Fig. 1; Fig. 3 is apartial longitudinal section taken at a right angle tothat of Fig.2, theends of the lamp bein broken away; Fig. 4 is an enlarged partial sectionsimilar to that of Fig. 2;

and Fig. 5 is a rear view of the slide forming a part of the switch.

The lamp is composed, as usual, of a casing a of hard rubber or otherinsulating material, which'is open at both ends. In one of these openends is fastened, by the usual threaded thimble b, the reflector b whichcarries the lam (not shown), and the other end through w 'ch the battery0 is inserted, is closed by a removable ca d. As usual, one terminal ofthe lamp ma es contact with one pole of the battery, while the otherterminal of the lamp is electrically connected to the metal reflector b.Inside the casing two longitudinall extending metal strips e, f areprovided, 0 which strip f, as usual, is in electric connection with thereflector b and is riveted to the casing. as at f, while the strip a iselectrically. connected to the other pole of the battery located at theopposite end of the latter.

Secured to the outside of the casing a is a box-shaped metal frame 9 inwhich 15 ar-' ranged the spring slide forming part of the circuit closeror switch. Thus far the construction is well known.

My invention resides in an improvement in the circuit closer or switchwhereby the latter is rendered more reliable and durable. Theimprovement consists in that the metal strip f at its free end is formedto a spring hook f which is adapted to project with its outwardlybulging surface into the box 9 through a narrow slot (1" in the casinga. The slide 72. is a flat metal piece having a rough outer surface andslidably bearing on the outer surface of the box or frame 9. The same isprovided with a neck portion h that projects through a narrow slot 9' ofthe frame 9 and carries inside the lattera spring plate 71 suitablyfastened to said neck. This spring plate at its upper end is also formedto a spring hook i which with its bulging surface is directed toward thecasing a and is adapted to normally bear on the latter as at a.

The metal strip e is conductively connected to the metal box or frame g,as by a rivet e. When the slide it is moved from its inoperative orcircuit openin position into the circuit closing position, tie springpart operativeness of the latter. 1

In order that the slide may be held in the circuit opening position whenthe lamp is not in use and that the life of the battery may thus belengthened, I provide an automatically working locking means for theslide.-

In the present embodiment of my inven-- tion this locking means consistsof a rounded projection gr extending from the inner sur ace of the frameor box 9 and adapted to engage acorrespondingly shaped depres sion z' inthe plate 2' when the slide is moved into inoperative position.

Since various modifications may be made in the structure withoutdeviating from the spirit of my invention, I do not wish to restrictniyself to the. details described and shown;

What I claim and desire to secure by Letters Patent is I 3 1. In acircuit closer, a casing having a circumferential aperture, a conductorstrip in said casing the free end of which is resilient and formed to apart bulging outwardly through said aperture and a second conductorconsisting of a slidable resilient member outside of said casing andhaving a part bulging" inwardly, the two bulging partsloeing adapted toconstantly project into oneanothers path and to close the circuit whenthe sliding member is moved into circuit closing position.

2. in a circuit closer, a casing having a circumferential aperture, abox fastened to the exterior of said casing over said aperture, aconductor consisting of a fiat slide lnovably guided in said box and aspring plate carried by said slide and having a part bulging toward saidcasing, and a sec- 0nd conductor consisting of a strip having a bulgingpart projecting through said aperture into the said box, said two springparts beini adapted to constantly project into one anot ers path and tocome H1130 contact with one another when the sllde' is moved intocircuit closing positron.

3. In a circuit closer, a casing having a circumferential aperture, abox fastened to the exterior of said casing over said aperture, aconductor consisting of a flat slide vmovably guided in said box and'aspring plate carried by said slide and having a part bulging toward saidcasing, a second conductor consisting of a stri bulging part projectingthrong ture into the said box, said two spring parts being adapted toconstantly project into one anothers path and to come into contacthaving a.- sald aper-= With one another when the slide is moved
